Ryufin missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

stock
get_stock_answers
Ryufin's five answers for one stock: is the business good, is it safe, is the price fair, is it growing, what is the market doing with it. Each answer has a one-word verdict, a plain sentence, the checks it was read from (with values and dates) and, when it moved recently, what it was before.
get_stock_overview
Price, market value, P/E, returns, sector, RyuScore (0 to 100 from seven weighted criteria) and what the company says it does, verbatim from its latest annual report.
answer
get_answer_changes
Stocks whose answer to one of the five questions changed in the latest nightly run (for example Safety from Good to Watch), largest companies first.
company
get_company_news
The company's own recent current reports (8-K), newest first: the date, what kind of event, the company's own sentence and a link to the filing on sec.gov.
financial
get_financial_history
A reported financial series for one stock from its SEC filings, trailing twelve months or single quarters, newest last. Metrics: pe, revenue, net_income, eps, gross_margin, op_margin, net_margin, roe, roa, roic, fcf.
stocks
search_stocks
Find US-listed companies Ryufin covers by ticker or company name. Returns ticker, name, sector, market value and the Ryufin page.

Ryufin — questions

Answers built from our own checks of this server.

What can Ryufin do?
It exposes 6 tools, read directly from the server on our last check. Among them: get_answer_changes, get_company_news, get_financial_history, get_stock_answers, get_stock_overview, search_stocks. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Ryufin working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 453 ms. The bar chart above shows every period we have measured.
How do I connect Ryufin?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Ryufin need an API key?
No. Ryufin completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Ryufin?
It answers our handshake in 453 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
